Dim order_type As DropDownList = _
(CType(e.Item.FindControl("order_type"), DropDownList))

Whenever I try and do anything further with this, it says:
Object reference not set to an instance of an object.
My guess is that that means it cannot find the control on the form.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
